The beautiful topological structure of the retardance distribution in a glass window with inhomogeneous stress (a stress-engineered optic or SEO) leads to a variety of intriguing optical physics, optical engineering, and applications. I will give a bit of the history of stress engineering applied to complex light fields, review some of the work related to polarization and polarization measurement, describe Full Poincaré Bessel beams formed from an SEO, and discuss current and future applications for single-shot characterization of complex fields such as those used in inertial confinement fusion experiments.
